reduction of methoxyketon 1 by nabh4 gives methoxyketol 2. allthough acetate and tosylate of this alchohol were not seprated, benzoate ester was isolated. reduction of ketol 2 by lialh4 gives alchohol 4. ketol 9 does not react with methyl magnesium iodide, but methoxyketon 1 react with both methyl magnesium iodide and phenyl magnesium iodide gives corresponding hydrocarbons. keton 13 with pheny...
Empaglifolzin reduces metabolic derangements such as BP (blood pressure), hyperglycemia, body weight, uric acid, increases Ht (hamtaocrit), keton bodies, and restores altered tubule-glomerular feedback, thereby protect against diabetes-induced caidio-renal injuries.
Chemical research and mountaineering have much in common. If the goal or the summit is to be reached, both initiative and determination as well as perseverance are required. But after the hard work it is a great joy to be at the goal or the peak with its splendid panorama. However, especially in chemical research as far as new territory is concerned the results may sometimes be quite different:...
(70% of theory) and >90% ee, as determined by NMR analysis of the derived ( + )-MTPA ester.5) Protection of (-)-6 by TBSC1 and imidazole afforded (-)-7f in 71% yield. Stereospecific alkylation of epoxide (-)-7 with phenylmagnesium bromide in the presence of Cul afforded the (-)-8f in 75% yield. Moffat oxidation (DCC, TFA, pyridine, DMSO, benzene) of (-)-8 furnished (-)-9t (88%). Finally, remova...
all analytical methods are generally based on the measurement of a parameter or parameters which are somehow related to the concentration of the species.an ideal analytical method is one in which the concentration of a species can be measured to a high degree precision and accuracy and with a high sensitivity. unfortunately finding such a method is very difficult or sometimes even impossible.in...
